Yangguan City (now southeast of Tai'an, Shandong) was originally the territory of the Ji family, and the size and status of the city were second only to Fei. After Yanghu came to power, he took it and the city of Zhencheng (now northwest of Ningyang, Shandong, very close to the Pingyin Pass) to himself, and through several years of operation, he built it into a strong fortress, and also made the two cities into a country within a country.

After Yang Hu fled into the city, he strengthened the city's defenses, and at the same time sent an envoy to the state of Qi, asking the Duke of Qi Jing to accept the two cities. Qi Jinggong was overjoyed, he said: "Deyang Tiger is equivalent to half of the Delu army, and Deyang Pass and Zhencheng are equivalent to the pass and pass of Delu country. If the state of Lu still refuses to submit, the widow will erase Qufu from the map of China. ”

Qi Jinggong sent an envoy to announce the appointment of Yang Hu as the doctor of Qi and took over the two cities. In three years, the state of Lu waged war against Qi, Zheng, and Wei; The Lu people made enemies on all sides, and now they were choked by Yanghu's neck, and they suddenly panicked. The Lu people did not dare to act rashly, so they had to strengthen their garrison and wait and see what happened.

Yang Hu thought that he would be able to sit back and relax if he continued to develop according to the current trend, but he knew that a traitor would soon appear around him. In the spring of the ninth year of the reign of Duke Luding, the Zai of Zhencheng Yi took advantage of Yanghu's departure and fled back to Qufu with the official seal, household registration and map. Official seals and documents were symbols of dominion, and the incident led the people of the city to believe that Yanghu's rebellion was doomed to failure.

The city was leaderless, people's hearts were fluctuating, and order was chaotic, and Yanghu sent people to take over the city, but the aborigines closed the city gates and refused to allow officials to enter the city. Ji's army soon arrived and recovered the city without much effort. As a result, Yangguan's position became isolated and precarious.

Many of the Ji clan's low-level retainers were coerced into the rebellion by Yang Hu. People are actually neither rebellious nor guilty of serious crimes; Many have even begun to plan the overthrow of Yang Hu.

Yang Hu has a hunch that if there are those people, Yang Guan will not be guaranteed. But he didn't want to hurt his colleagues who had been with him for many years, so he handed them the treasure jade and the bow he had stolen from the palace and asked them to return to the capital with the treasures. Those people were later pardoned by Ji Huanzi.

After the recovery of the city, the people of Qi did not react violently; The people of Lu decided to strike while the iron was hot and recover Yangguan in one fell swoop.

In June, Ji Huanzi and Meng Yizi besieged Yangguan. The west of Yangguan is close to Mount Tai, and the three sides are plains. Yang Hu climbed the city wall and looked around, and everywhere he saw were military camps, only a small number of enemy troops were stationed on the west side of the city due to the terrain. The Lu army attacked for a few days but had little success. Ji Huanzi then ordered a truce, and at the same time began to manufacture a large number of siege equipment.

Yang Hu knew in his heart that it was pointless to hold on to the city, so he made a bold breakthrough plan. Yang Hu sent a letter to Ji Huanzi, in which he declared that he would start a dignified battle with him in the southern suburbs of Yangguan, and the victory would be determined in a battle. Ji Huanzi really couldn't figure out Yang Hu's intentions (unless he was already crazy or wanted to commit suicide), and after careful consideration, he agreed to fight him. After the envoy left, Ji Huanzi mobilized some troops from the north and west of the city to strengthen the power in the south of the city.

On the night before the decisive battle, Yangguan City was already shrouded in endless darkness due to the control of the lights. The Lu army outside the north gate also entered sleep mode, only the campfires in the camp were flickering, and the sentinels in charge of watchout were paying attention to the direction of the city.

Suddenly, countless torches suddenly lit up on the walls of Yangzhou City, countless figures appeared, and people were pouring some liquid under the city; Then the torches were thrown, and the entire wall was enveloped in flames.

The sentinels struck the Golden Duo violently, and a piercing noise resounded through the sky; The sleeping soldiers were instantly awakened, frightened one by one, and then searched everywhere for weapons and armor.

The city gate suddenly opened, and a death squad rushed out of the city, led by Yang Hu. After the team rushed out, the people of Yangguan actually set the city gate on fire, and the raging fire was weighed one after another, scorching the entire city wall. From the perspective of the public army, the city has become a burning purgatory; And the death squad with teeth and claws is the ghost demon who has been killed from purgatory.

The barracks were in chaos. At this time, Ji Huanzihe Meng Yizi had already brought the main force to the south of the city, and there were not many troops in the northern camp. The battalion commander was young and inexperienced, so he did not organize the defensive line in time. As a result, the vicious team rushed through the camp and disappeared into darkness as if it were "Yin soldiers transiting".

Yang Hu fled into Ping ** overnight, and then stopped to catch his breath. He entered Linzi a few days later.

Qi Jinggong was very excited about Yang Hu's arrival, and entertained him with the courtesy of a minister. Yang Hu did not hide his thoughts, and said straight to the point: "The reason why I came to Linzi is to dedicate the Lu State to the prince and make the Great Qi Kingdom unify the East." Please believe that if I am ordered to command the Qi army, I will definitely capture Qufu and destroy Sanhuan in only three battles! ”

Qi Jinggong was even more passionate when he heard this, but he only cared about drinking with Yang Hu that day, and did not make a decision on the spot.

The next day, Bao Wenzi (Bao Guo), an old man of the Three Dynasties who was over ninety years old and was idle in bed, heard about this and ordered his retainers to carry him into the palace to meet Qi Jinggong.

Bao Guo said: "The prince must not be bewitched by the Yang Tiger! Chen used to be Uncle Shi Xiao's retainer (seventy-three years ago, Qi Linggong cut off Bao Lian's foot due to Gao Wujiao and the Guozuo Rebellion, so Bao Guo, who was a retainer in Uncle Shi Xiao's house, was recalled to inherit the throne), and he knew the situation of Lu very well: Lu was in harmony with the whole country, could concentrate on serving the great country, and there was no natural disaster, so it was impossible to be destroyed!

"As far as the minister can see, once the prince and marquis give the military power to Yang Hu, the Qi division will inevitably be tossed and exhausted by him. At that time, the soldiers suffered heavy casualties, and Yang Hu had a chance to realize his plot - he was probably trying to usurp the position of the prince, right? Yang Hu was favored by Ji Pingzi, but wanted to kill his son; He did not allow Yu Lu to be exiled here. How can this man, who is greedy for wealth and wealth but abandons righteousness, be appointed by a prince? The prince is far richer than the Ji family, and the Qi country is far greater than the Lu state; Qi and Lu fought and both were defeated, this is the real purpose that Yang Hu asked Valu to achieve! The country of Lu expelled the scourge, but the prince took him in again, aren't you afraid of the calamity yourself? ”

Only then did Qi Jinggong come to his senses, and he asked thoughtfully: "According to the master's will, not only can the widow not use him, but also punish him for his sins?" ”

Bao Guo said: "Everything is judged by the king!" ”

After Bao Guo left, Qi Jinggong summoned Yang Hu. Yang Hu was full of joy and was taken down by the guards as soon as he stepped into the palace gate. The army immediately surrounded the residence of the exiles brought by Yang Hu, and wiped out those people as well.

On the issue of how to deal with Yang Hu and him, the people of Qi felt very embarrassed. After some discussion, Qi Jinggong decided to exile him to an isolated island in the East China Sea; More than fifty years ago, Duke Qi Zhuang sent Luan Ying and his henchmen to that island to protect them.

The Qi people announced the decision to exile Yang Hu, and Yang Hu expressed his obedience. The Qi people then moved him and his followers to a small town in the west of the city and put them under centralized care, preparing to take them to the sea.

Although Yang Hu has lost his freedom, his entourage still has room to move. Yang Hu approached the magistrate of Xiaoyi, gave him some benefits, and asked him to be allowed to bring back the belongings left in Linzi. In this way, all the vehicles in the area were loaned out. Yang Hu explicitly asked his followers to take the vehicle to transport the goods, but secretly gave them the order to destroy the axles.

The followers faithfully carried out their task: they carved a deep groove in the middle of the axle with a sharp object, and wrapped the incision with silk mahjong.

After the vehicle returned to Xiaoyi, Yang Hu ordered a lot of clothes to be loaded onto an undamaged car, and then got into the pile of clothes. An attendant drove the car through the city gates. When the soldiers questioned him, he said that these were all "gifts" from Yang Hu to a certain commander, and Yang Hu deceived the soldiers and fled from the place.

Later that day, the car still hadn't returned, and the magistrate realized something was wrong. He immediately led his army to Yang Hu's shelter, only to be told that Yang Hu was resting. The magistrate forced his way into Yang Hu's room, only to find that he was not indoors at all.

The magistrate scolded Yang Hu for being "treacherous and cunning" and ordered a vehicle to chase after him. But the result should be expected: the vehicle can still drive normally when it first starts, but when it accelerates to a certain speed, the axle breaks because it can't withstand the huge impact force; As a result, the carriages fell to the ground and fell apart, and the people on the bus also fell with bruised noses and swollen faces, broken tendons and fractures.

Later, the people borrowed a number of chariots from the nearby Xiaoyi, and after a day of pursuit, they finally captured the exhausted Yang Hu at dusk the next day.

The Qi people imprisoned him in Linzi this time, but he repeated his old tricks and escaped in a cart loaded with clothes. Yang Hu first fled to the Song Kingdom, but the Song people did not welcome him very well; He fled to the Jin Kingdom again, and finally surrendered to Zhao Jianzi.
